Originally a sub-unit of the idol group Music/SakuraGakuin, [=BabyMetal=] (also stylized as BABYMETAL) was formed by the members of the Heavy Music Club of Sakura Gakuin, under the concept of a fusion of "heavy metal and idol music". [=BabyMetal=] released their first single "BABYMETAL × Kiba of Akiba" in March 2012, reaching the 3rd place in the Oricon indie charts and number one in the Tower Records Shibuya weekly indie ranking. However, it wasn't until they released their second single, [[http://www.youtube.com/watch?v=2IzR_ClTE8Y "Headbangeeeeerrrrr!!!!!"]], that they became popular outside of Japan. The video went viral quickly and the sub-unit managed to become a stand-alone group. In 2014 they did a 2-day Budokan concert[[note]]10000 spectators each day[[/note]] and released their eponymous first album. The video for ''Gimme Chocolate!!'' was released just before the Budokan concert and promptly went viral, to the extent that non-Japanese [[UsefulNotes/MainstreamMedia mainstream media]] picked it up.

At the Budokan concert it was announced that the first chapter of the Metal Resistance was over, and BABYMETAL would continue their training overseas. Dates in Paris, Cologne, Knebworth[[note]][=SoniSphere=] 2015[[/note]], London and Los Angeles followed, along with opening slots for Music/LadyGaga. These went well enough that further dates in New York and London[[note]]this time in the Brixton Academy[[/note]] were hurriedly arranged. During the Brixton show a new song ''Road of Resistance'' was performed[[note]]this was the first time a new song had been unveiled outside Japan[[/note]].

Following a January performance at the Saitama Super Arena, 2015 was quiet as Yui and Moa concentrated on their final months in Sakura Gakuin. After their graduation dates both in Japan and abroad followed culminating in two nights at the Yokohama Arena. It was also announced that their second album would be released on 1 April 2016, with a performance at the SSE Arena Wembley the following day. This album, ''Metal Resistance'', was launched with a significant amount of international coverage, including an appearance on the Series/TheLateShowWithStephenColbert. The 2016 world tour was capped with two sold-out nights at the 55000 capacity Tokyo Dome.

!!Tropes da o!
* TheAce
** Suzuka for singing. The creator of the group had been looking for some years for someone to train up as a metal idol. Then he saw Suzuka performing in Karen Girl's (age 11) and the rest is history.
** Yui for dancing. Although the other two are no slouches either.
** Moa for crowd engagement.
* AnimalMotif: Foxes.
* AnnoyingYoungerSibling:
** Suzuka can be this to her sister, Himeka (of Nogizaka46). In particular, has a habit of raiding Himeka's wardrobe whenever she feels like it.
** On occasion, Yui's younger brother (On a radio program Yui's choice of 'death metal scream' consisted of 'get up, you lazy piiiiig!' - ending on a pitch that could stun bats).
* AscendedExtra: They're even more popular than their parent group, Music/SakuraGakuin.
* AudienceParticipationSong: Judging by Website/YouTube videos, most songs during concerts have audience participation segments. Oh, and festival performances of ''Ijime, Dame, Zettai'' encourage a Wall of Death...
* BadassAdorable: A large part of the appeal.
* BadassCape: During live performances of ''Akatsuki'' (a Suzuka solo).
** For all three members in performances of ''THE ONE''.
* BilingualBonus: Many songs contain the occasional English word or phrase, but the most notable example is their concert opener, Babymetal Death - a deliberate bilingual pun, since what they're actually shouting is Babymetal Desu (I am Babymetal), but the pronunciation of "Desu" is similar to the English "Death" - a fact not lost on the promoters.
** "The One" has more English in it than Japanese
* ButNowIMustGo: Averted. Sakura Gakuin only accepts members under 15 years old, and when the current members reach this age, they must graduate. When Suzuka became 15, she left the main group, but the management made [=BabyMetal=] a separate unit, thus allowing them to be active. Yui and Moa graduated in 2015, so now all members are independent of Sakura Gakuin.
* ChildProdigy: Yui and Moa were talented enough to join Sakura Gakuin at the age of 11 (and produce ''Doki Doki☆Morning'' one year later). And before Sakura Gakuin, Suzuka was in a group called Karen Girl's doing the opening theme of ''Manga/ZettaiKarenChildren''. And that's not counting the other stuff they've done...
* CreepyCoolCrosses: They use it a lot. Special mention goes to Suzuka's 16th birthday, when she was ''crucified''.
* DarkerAndEdgier: Compared to other idol groups.
* DrumAndBass: "Awadama Fever" is this.
* EarlyInstallmentWeirdness: Their first song, ''Doki Doki☆Morning'', had a more distinct "idol-like" sound than their following songs.
** ''Doki Doki☆Morning'' appeared to have a very low budget (and most of that probably went on the music). The costumes used in the video were made up from a combination of the girl's clothes (and some from a staff member for Suzuka). The next video (as uploaded to Youtube) for ''Iine!'' shows them in the same costumes. The third video for ''Headbangeeeeerrrrr!!!!!'' sees them use the costumes that are recognizably related to their established look.
* [[ExcitedShowTitle Excited Song Title!]]: Their song ''Iine!''.
** Also ''Headbangeeeeerrrrr!!!!!''
** ''Gimme Chocolate!!''
* FourIsDeath: The Black Babymetal song "Song 4" (which uses a lot of wordplay surrounding the readings of "4" in Japanese) seems to refute this with a line in the chorus stating that 4 is not synonymous with death.
* GenreRoulette: Fairly uniquely for a pop-metal band, the actual metal isn't tethered to a specific sub genre. It varies from BlackMetal, to MelodicDeathMetal, to {{Djent}}.
* GirlishPigtails: Moa and Yui's usual hairstyle. Suzuka started out having these too.
* HeWhoMustNotBeSeen: The musicians during their early years wore skeleton costumes in the music videos and while appearing in public. Except in ''Megitsune''... where they wear long black wigs and masks. In reality, they were just faking playing to a backing track.
** HeWhoMustNotBeHeard: When the musicians themselves (including the producer) get interviews, all they do on-screen is mumble and subtitles of what they're actually trying to say are shown.
** Averted in concerts from 2013 onwards - they now have a live band wearing white robes and facepaint, composed of members of Japanese rock / metal groups. There's a semi-regular lineup, although members can be swapped out if they have availability issues.
* HimeCut: When they let down their hair, it resembles this style and given their genre of Heavy Metal, it makes quite the contrast with the trope's usual connotations of tradition and elegance. Suzuka plays it the straightest (figuratively given her leaderness and literally too), and she's done so in certain music videos such as ''Megitsune''.
* IAmSong: "Babymetal Death" is an extreme example, since pretty much the only lyrics are the group introducing themselves.
* IconicOutfit: Their outfits deriving from the video for ''Ijime, Dame, Zettai'', featured in the picture to the right. Now used in most live concerts.
** Also the early era musicians' skeleton costumes / loose white robes of the current musicians.
* IdolSinger
* {{Kawaiiko}}: Moa and Yui.
* {{Kitsune}}: The main theme of ''Megitsune''.
** The theme of the group itself, with its fox sign. They're always seen doing it, such as in the image above.
* TheLeader: Suzuka. Also the FaceOfTheBand.
* LighterAndSofter: Than most heavy metal bands. To wit, one of AmonAmarth's songs was about the fated clash to the death between Thor and the World Serpent (Twilight of the Thunder God), one of JudasPriest's songs was about the circumstances that lead people into a life of crime (Breaking the Law). What was Babymetal's first song about? ''Chocolate''.
* LoudnessWar: Their music is all brickwalled and almost pure clipping from start to finish. This may be an intended effect though...
** The production of the second album ''Metal Resistance'' is better than the first, although the dynamic range is similar.
** The live albums ''Live at Budokan: Red Night'' and ''Live at Budokan: Black Night'', mastered by Ted Jensen, are quite reasonable by modern standards.
* LuckyCharmsTitle: ''Doki Doki☆Morning'', ''Uki Uki ★ Midnight''.
* MindScrew: What this idol group is to metal purists. Though many of them somehow like the group...
* MohsScaleOfRockAndMetalHardness: On average, a hard 6 to a soft 7, though "Megitsune" is a borderline 8.
** "Babymetal DEATH" seems to go as far as a 9, with most of the vocals being death growls and metal screams and having nearly none of the super-happy cuteness factor a lot of their other songs have.
** The second album ''Metal Resistance'' goes up to 9 in several tracks.
* NeoclassicalPunkZydecoRockabilly: Combines the hardness and energy of heavy metal with the catchiness and appeal of J-pop and a VisualKei-influenced sensibility.
* NervesOfSteel
** Karen Girl's did their final live performance at an anime festival at the Saitama Super Arena[[note]]the largest venue by far they had played, with a capacity of 20000[[/note]]. Several years later the other two group members[[note]]Ayami Muto and Yuika Shima[[/note]] related that they were both extremely nervous before their performance. Meanwhile, Suzuka was snoozing in the dressing room and had to be woken up in time to perform.
** You would expect most teenage Japanese girls to be more than a bit nervous when facing 50000 British metalheads at their first appearance in the UK[[note]][=SoniSphere=] 2014[[/note]]. If they were it was not at all obvious...
* PunctuatedForEmphasis: ''Ijime, Dame, Zettai'' (''No, More, Bullying'') is a strange example.
* RatedMForManly: The inversion of this trope is the whole point of this band.
* RedOniBlueOni: Moa and Yui to a certain extent - Moa Red, Yui Blue.
** "Catch Me If You Can" is about the girls hiding from very hungry oni who want to eat them.
* SilkHidingSteel: One of the themes in "Megitsune".
* SongStyleShift: "Iine!" has a ''[[TrapMusic Trap]]'' break near the middle, complete with hoodies, GratuitousEnglish, and Music/KanyeWest [[http://1.bp.blogspot.com/_txdFVAWpc94/TOKwqIGfagI/AAAAAAAAA4o/JMPJAXyX6xY/s640/kanye_west_daft_punk_stronger_01.jpg sunglasses.]] [[http://www.youtube.com/watch?v=qVdBBOpSoN4&t=1m33s We are completely serious.]] Apparently it's done as a TakeThat to SwagRap.
** "Uki Uki ★ Midnight" has a {{Dubstep}} break, [[http://www.youtube.com/watch?v=W-2Z_kQpdW0&t=1m36s also near the middle.]]
** "Song 4" also features a reggae section.
* SpellMyNameWithAnS: ''Iine!'' faces the same problem as ''[[Music/{{Loituma}} Ievan Polkka]]''. Three guesses on what that problem is and the first two don't count.
* SureLetsGoWithThat: At the beginning of the group the manager was trying to teach the members the [[WardingGestures heavy metal horns]] gesture. They misinterpreted the description and made the a 'kitsune sign' instead. The whole Fox God mythology of the group probably stems from this.
* ThatSyncingFeeling: Early live performances were mostly lipsynced, with some live vocals blended in (quite common for idol performances). Later on Suzuka did more and more live, followed by Yui and Moa. The production of the ''LIVE AT BUDOKAN'' albums (2015) makes it very easy to hear that the backing vocals are confined to a few parts of the Black Babymetal songs (mostly parts with strenuous choreography).
* TitleScream[=/=]MetalScream: ''HEADBANGEEEEERRRRR!!!!!''
* TomboyishPonytail: Suzuka's usual hairstyle.
* [[WidgetSeries Widget Musicians]]: Three {{Idol Singer}}s mix pop music with HeavyMetal. It works and it's... ''[[CrowningMusicOfAwesome it's totally awesome]]''. Oh, UsefulNotes/{{Japan}}...
* ZettaiRyouiki: Grade B when wearing socks. Averted in 2013 when the uniform used stockings, apparently again for 2016.
